Chevrolet Express Owner Manual - 2011
9-32 Driving and Operating
Grade Braking is only active while
the Tow/Haul Mode is selected and
you are not in the Range Selection
Mode. See “Tow/Haul Mode” listed
previously and Manual Mode on
page 9‑30 for more information on
the Range Selection Mode. Grade
Braking assists in maintaining
desired vehicle speeds when driving
on downhill grades by automatically
shifting to lower gears when the
driver desires to slow the vehicle by
applying the brake. This reduces
wear on the braking system and
increases control of the vehicle.
Also see Trailer Towing on
page 9‑48 for more information.
Cruise Grade Braking
(Six Speed Automatic
Transmission)
Cruise Grade Braking operates only
while Cruise Control is engaged in
Tow/Haul Mode. Cruise Grade
Braking assists in maintaining
desired vehicle speeds when driving
on downhill grades in cruise control
by automatically shifting to lower
gears when the cruise set speed is
exceeded.
While in the Range Selection Mode,
Cruise Grade Braking is not
available.
See Manual Mode on page 9‑30.
Drive Systems
All-Wheel Drive
If the vehicle has this feature,
engine power is sent to all four
wheels when extra traction is
needed. This is like four-wheel
drive, but there is no separate lever
or switch to engage or disengage
the front axle. It is fully automatic,
and adjusts itself as needed for
road conditions.
